No. 874,088. Renewed-April 28, 1909. Serial No. 492,768.

To all whom it may concern;

Be it known that I,.Gnoncn S. TIFFANY,

a citizen of the United States, residing at.

Summit, county of Union, and State of New Jersey, have invented certain newand useful Improvements in Telautographs, fully described and epresented in the following specification and the accompanying drawings, forming a part of the same.

The invention of this application, which is a division of'an application filed by me July 6, 1906, Serial No. 324,960, relates to improvements in paper shifting mechanisms for the receiving instrument of telautographic systems; it being the object of the present invention to PI'OVldG a shifting mechanism controlled from thedistanttransmitting instrument and which will-not only feed. the paper step by step over the writing field of the receiver a distance at each step equal to thefeed of the paper at the transmitting instrument, but will also store or reel up the strip as written .npon so that a permanent and convenient chronological record may be had of messages-received.

Figures 1" and 2 are diagrammatic views of the transmitting and receiving instru ments, respectively, of a telautographic system equipped with paper shifting mechanism embodying the present invention. Figs.

3 and 4 are end elevations, and Fig. 5 a front elevation, of the paper shifting mechanism embodying the present invention.

The telautographic apparatus shown in the drawings is 1dentical with that illustrated in my prior application aforesaid, and said apparatus therefore need only be described briefly here, reference-being made to said application for a more detailed description thereof. a

The apparatus. shown is of the type in which the lateral movements of the receiving pen'are efl'ected by variations in the current strength on the two main lines from the transmitting instrument, such variations in current strength being in turn effected by the lateral movements of the transmitting tracer in writing, so that, as the tracer is thus moved laterally, the receiving pen is moved in the same direction and to the same extent and will thus reproduce the move- 'ments' of and writing performed by the transmitting tracer.

The source of energy for the main line circuits is a battery 1 at the transmitting instrument, the currents from which are shunted into the main line circuits through a pair of rheostats 2, 3. The transmitting.

instrument is also provided with .an oscillating master switch 40f suitable insulating material provided with a series of contact plates 5, 6, 7, 8, 9, 10, coacting with a series of contact springs 11, 12, 13, 14, and through the latter controlling the making and breaking of the two main line circuits to the distant receiver (Fig. 2) as well as the independent circuit or circuits connectingrheostats 2, 3 with battery 1. Contact plates 5 and 10 are connectedtogether, as shown in Fig. 1, as are also contact plates 6 and 9, for a purpose hereinafter explained.

Themaster switch 4, as shown in Fig. 1, is in. position'for the transmission of mes sages to the distant receiver (Fig. 2). In

time position the independent circuit from battery 1 1s closed, this circuit consistin of wire 15 from the positive pole of said attery, contact spring 11, contact plate 5, on masterswitch 4, and wire 16where the circuit divides, one art of the circuitconsisting of wire 17,1e hand. rheostat 2, wire.,..18,

wire 19, contact plate 6 on master switch 4,

contact spring 12, and wire 20 to the negative pole of battery, while the other part of the circuit consists of wire 21, right hand rheostat 3, wire 22, wire 23, wire 19, contact plate 6, and wire 20'to the negative pole of the battery,-this pole of the battery being connectedwith ground by wires 23, 24-. In this position of master switch also, the two main line circuits to the distant receiver are also closed. The left hand main line circuit consists (Fig. 1) of a contact roller 25-, an

arm 26 carrying it, wire 27, contact plate 7 on master switch 4, contact spring 13, wire 28,.and (Fi 2) wire 28, the winding of a. olarized re ay-29, wire 30 leading there. rom, one windin 31 of a relay 32 (which has a second winding 33), wire 34, to ground, and (Fig. 1) from ground, by wires 24l,-23,'19, contact plate 6, contact 12, and wire 20 to the negative pole -of battery 1. The right hand main line circuit consists of contact roller 35, arm 36 carrying 37, secondary winding 38 of an induction coil, wire 39', contact plate 8 on the master it, wire switch 4, contact spring 14, wire 40, and (Ijig. 2) wire 40, the winding of a relay 41,

wire 42, one win ding 43 of a relay 44 (correspending to relay 31 and having a second windin 45), wires 46, 47 to ground, and (Fig. 1 from ground, by wires 24, 23, 19 contact plate 6, contact 12, and wire 20 to the negative (pole of battery 1. Arms 26, 36

are connecte rigidly with arms 48, 49, re spectively, each pair of arms 26, 48 and 36, 49' being pivotal y mounted, as at 50, so as to swing freely in a horizontal direction, and said arms 48, 49 have connected with them, by ball and socket joints, a pair of arms 51, 52, respectively, in the converging pivotall connected ends of which is mounted the transmitting tracer 53.

As fully described in my aforesaid prior application, when the master switch 4 is in the position shown and the transmitting tracer 53 is moved laterally, as in Writing, contact rollers 25, 35 are moved along rheostats 2, 3, respectively, assuming different positions along them according to the direction and extent to which the tracer 53 is moved laterally, and positive currents, vary ing in strength in accordance with the lateral movements of the tracer, will therefore be shunted from battery 1, through rheostats 2, 3 into the left andright main line circuits just described. The .currents thus shunted into the left main line circuit pass loosely by Wires 28, 30, 34, through relays 29, 32'

at the left hand side of the receiving instrument, while those shunted into main line circuit pass, by wires 40, 42', 46, 47, through relays 41, 44, at the right hand side of the receiving instrument. Relays 32, 44 control a pair of magnets 54, 55, included in a local circuit from a battery 56, and which in turn control the lateral movements of the receiving pen 57; relay 41 controls a pen lifting magnet 58 which in turn controls the movements of the receiving pen to and from its writin field; and polarized relay 29 controls the local circuit just referred to from battery 56 and also the operation of the paper shifting mechanism constituting the present invention. These devices, and the circuits and other devices with which they are shown connected, are fully described in my prior application aforesaid, and for this reason they need not be further described here except in so far as the polarized relay29 and its control of the paper shifting mechanism are concerned. Before de scribing this aper shifting mechanism, it may be well to note that when ositive currents traverse the main lines rom battery I, as in writing and as in the case when master switch 4 is in the position shown, that traversing the left main line will bias armature 59 of relay 29 against a contact 60 and thus close the local circuit reiferred to from battery 56 through magnets the right seams 54,55, and that when, as will hereinafter appear, the current traversing the left main line from battery 1 is reversed, armature 59 will be biased away from contact 60, thus opening this local circuit. This reversal, in direction, of the current traversing the left main line, is controlled by the master switch 4 at the transmitting instrument, as will presently appear.

The paper shifting mechanism at the receiving instrument consists of a reel 61, journaled in standards 62, 63, and on which the leading end of the record strip 64 for the receiving pen is wound; a spring barrel 65 provided with a gear 66 meshing with a pinion 67 on the shaft of reel 61, (the tendency of said barrel being to rotate said reel to wind the strip 64 thereon) and a pair of retarding rollers 68, 69 between which said strip passes on its way from the writing field of the receiving pen to the wind-up reel 61, and which normally resist movement of the strip. The roller 68 is journaled in standards 70, 71, while the roller 69 is journaled in the ends of arms 72 pivotally mounted in said standards, a spring or springs 73, connected with said standards and arms, or one of each, serving to hold the roller 69 yieldingly engaged with roller 68, with the paper strip 64 between them. The barrel 65 turns on a shaft 74 journaled in standard 63 and provided with a handle 75 by which it may be rotated, and said barrel contains a coiled spring 76, the outer end whereof is connected with the barrel, its inner end being connected with shaft 74. This spring is wound up by turning handle 75 and shaft 74 in a counterclockwise direction, retrograde movement of the handle and shaft when the spring is so wound being prevented by a spring pressed pin 77 inserted in a hole in standard 63 and adapted to engage a shoulder 78 on the hub of the handle. When spring 7 6 is thus wound up its tendenc is to turn in the direction of the arrow, igs. 3, 4, and rotate reel 61, but this tendency is resisted by the retarding rolls 68, 69, which in turn are normally held against rotation by means which will now be described.

Referring to Figs. 3-5 it will be observed that the shaft 79 of roll 68 has fixed to its left hand end a disk 80, the outer face of which is provided with two concentric rows of pins 81, 82, which are designed to be alternately engaged by a tail piece 83 (see Fig. 2) with which the armature 59 of John'- ized relay 29 is provided, rotation of rolls 68, 69, and therefore movement onward of strip 64, being prevented while said tail piciee is so engaged with any of said pins. The -tail piece is disengaged from a pin 81 or 82,;as the case may be, in the following manner: As the parts are shown in Fig. 2 a positive current is on line from the transeseeia springs 11, 12, which will then contact with contact plates-9, 10, respectively, on master switch 4. As before stated, contact plate 5 is electrically connected with contact plate 10, while contact plate 6 is electrically connected with contact plate 9, so that when the master switch 4 is thus rocked the polarity of the current from battery 1, in

0th main line-*cirfiits will be reversed. Armature 59 of polarized relay 29 will therefore be moved away from stop '60 and its tail piece-83 swung inwardly out of engagement with the pin 81 in the outer row on disk 80 and into position for engagement with the following pin 82 in the inner row,

the pins in the two rows being staggered as shown. Barrel 65 will then rotate reel 61 and wind strip 64 thereon until movement of the latter 1s arrested by engagement of tail pieces 83 with the next following pin 82 in the inner row. Master switch 4 being then rocked rearwardly to the position shown in Fig. 1, the polarity of the current on line is again reversed to positive, armature 59 reassuming the positlon in which'it is shown in Fig. 2 and tail piece 83 passin out of engagement with the mum in 82 an into position for engagement wit the next followin pin 81 in the outer row, thus permitting imther movement of strip 64. This rocking movement of the master switch 4 also shifts the paper strip 84 at the transmitter as described in my said prior application. With the paper shifting mechanism at the transmitter and that just described at the receiver properly adjusted with relation to each. other, it will be obvious that each time master switch 4 is thus rocked to shift the paper at the transmitter, the aper at the receiver will be correspon ingly shifted a like amount, and further, that by rocking the master switch 4 back and forth, the paper at the transmitter may be shifted to any extent desired by the transmitter operator.
